Summary

vLLM, open-sourced by UC Berkeley's Sky Computing Lab, is a high-performance LLM inference and serving library. Through PagedAttention and continuous batching, it dramatically improves throughput and reduces VRAM waste, while being compatible with the OpenAI API and various hardware.

Stop using vanilla HuggingFace to brute-force local LLM inference — VRAM instantly maxes out, and throughput is as slow as a turtle! vLLM from Berkeley Lab uses the PagedAttention trick from OS memory paging to squeeze GPU VRAM to its limits, reducing KV Cache VRAM waste to nearly zero. Continuous Batching plus an OpenAI-compatible API makes this the absolute performance king for deploying open-source models (Llama / Qwen / DeepSeek). Project Info • GitHub: vllm-project/vllm • Stats: 40k+ Stars | Apache 2.0 open-source license • Source: UC Berkeley Sky Computing Lab Core Highlights • Doubled throughput: 2-24x higher throughput than traditional inference engines, able to handle extremely high concurrent requests. • Zero VRAM waste: Unique PagedAttention maximizes VRAM utilization, making OOM unlikely even with very long contexts. • Plug and play: Built-in OpenAI-compatible API server, replace existing interfaces with just two lines of code. • Full hardware support: Supports NVIDIA GPUs, AMD, Intel XPU, and even CPU, covering nearly all open-source models.
